ROBERT D. PARKS, OF PLEASANT MOUNDS, MINNESOTA.

ACETYLENE- GAS GENERATOR.

SPECIFICATION forming part of Letters Patent N 0. 621,616, dated March 21, 1899.

Application filed April 14, 1898.

To @ZZ whom it may concern:

Be it known that I, ROBERT D. PARKS, of

Pleasant Mounds, in the county of Blue Earth and State of Minnesota, have invented a new and Improved Acetylene-Gas Generator, 'of which the following is a full, clear, and exact description.

VThe object of the invention is to provide a new and improved acetylene-gas generator arranged to generate gas only as 'required for consumption by automatically controlling the Water-supply to a small portion of the charge of calcium carbid and by keeping the main portion of the carbid in a magazine free and clear from the water and the hydrate of lime.

The invention consists of novel features and parts and combinations of lthe same, as will be described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure lis a sectional side elevation of the improvement on the line 1 1 of Fig. 3. Fig. 2 is an enlarged sectional side elevation of the adjacent pipes of the water-supply and waterdelivery pipes. Fig. 3 is a plan view of the improvement with parts in section, and Fig. 4 is a sectional plan view of the generator on the line 4 4. of Fig. l.

'The improved acetylene-gas generator is provided with a generator proper, A, and a gasometer B, having the usual tank B and the bell B2. The generator is provided With a casing'A, having a cover A2, formed with a downwardly-extending annular flange A2, reaching into water or other sealing liquid contained in a small tank A4, carried on the upper end of the casing A', the top of Which terminates a short distance from the cover A2, and the latter is removably connected by bolts A5 With the said tank A4.

In the casing A is set loosely an ash-receiver C, in the upper portion of which extends a calcium-carbid supportD, formed with a centrally-arranged cone D', supporting at its base a basket D2, the outer edge of which reaches close to the inner face ofthe ash-receiver C. The basket D2 is formed of wires and'is shaped like an annular trough, so that Serial No. 677,576. (No model.)

the hydrate of lime or other residue from the decomposed calcium carbid can readily drop between the wires down intothe ash-receiver C. The cone D', as Well as the basket D2, is secured to a vertically-disposed rod D2, set at its lower end in a suitable step C on the bottom of the ash-receiver O, the upper end of said rod extending through a Water seal E to the outside of the casing. The upper end of the rod D2is provided with a suitable handle D4, adapted to be taken hold of by the operator should it be necessary to turn or shake the rod D2, and consequently the carbid-support, so that the hydrate of lime is agitated and readily drops through the Wires of the basket down into the ash-receiver C.

A magazine F in the shape of an openended cylinder is supported by brackets F from the casing A directly above the calciumcarbid support D, the lower edge ofthe magaa zine being somewhat Within the outer edge of the basket D2, as will be readily understood by reference to Fig. 1. The magazine F is filled with a large amount of calcium carbid, and as the cone D extends up into said magazine it is evident that the calcium carbid passes down from the magazine onto the support D-that is, over the cone D down into the basket D2-to be there charged at the outer end of the basket and outside of the magazine F with Water for generating the acetylene gas.

The water for the generation of the gas is delivered to the calcium carbid in the basket.

D2 in a series of drops from a Water-delivery pipe G surrounding thel magazine F and formed With spaced minute openings in the top, as is plainly shown in Fig. 3,l so that the water passing into the pipe G passes out through the said openings to then drop downward outside of the magazine F into the carbid contained in the outer portion of the basket D2. The pipe G is supported by bolts G' from the cover A2 and is connected with a pipe G2, formed into a trap G2, extending into the water contained in the tank A4, to then extend upward through the cover A2.

The upper end of the pipe G2 is provided With a funnel G4, containing a sieve G5, and into said funnel G4 discharges a Water-sup; ply pipe H, fulcrumed at H' to a branch pipe ICO H2, provided with a valve H2 and attached to the tank B' of the gasoineter, so that the water contained in the said tank can readily pass through the said pipe H2 into the pipe H to finally ow into the funnel G4 and down the pipe G2 to the pipe G for delivery in drops to the carbid, as previously explained. The pipe H2 is connected with the tank B', at or near the upper end thereof, below the waterlevel, so that water only flows, through the pipe H to the funnel G4 when the pipe 4H is in a horizontal or downwardly-inclined position; but the pipe His adapted to be swn ng upward by the action of the gasometer-bell B2 to bring` the free end of the said pipe above the level of the water contained in the tank B', so that the water does not flow out of the pipe H to the pipe G2. For this purpose the pipe H is connected near its free end with one end of a rope I, extending upward and passing over a pulley I', journaled in a bracket I2, secured to the gasoineter-bell B2, the lower end of the rope I carrying a weight I2. On the rope I is also secured a lug I4, adapted to move in Contact with the peripheral surface of the pulley I' to prevent the weight I3 from drawing the rope I farther downward over the pulley l' at the time the bell B2 moves approximately into a lowerlnost position. 4

The gas generated in the generator A is delivered to the gasometer-bell B2 by a gas-pipe J, formed into a coil J', extending' through the water contained in the tank B', so that the gas in its passage from the generator A to the bell B2 is cooled. The lower end J2 of the coil J' connects with a valve J 2, supporting a valved condenser-Casin g J 4, in which the water of condensation may accumulate. A pipe J5, leading upwardly from the valve J2, extends through a water seal E' into a pipe JG, having a valve J7, from which leads a pipe JB through the tank A4 into the upper end of the casing A to -allowthe gas to pass from the latter through the several pipe connec.

tions, as described, into the bell B2. A pipe K also leads from the bell B2 to carry off the gas tothe burners. The bell B2 is provided at its lower end with a suitable weight B4 to give the desired pressure to the gas contained in the bell. A funnel B3 is connected with the upper end of the tank vB for supplying the latter with the necessary amount of water.

The operation is as follows: When the machine is in operation and the magazine F is lled with calcium carbid, then the lower portion thereof gradually feeds Vinto the basket D2, as previously explained, to be acted on by the jets of water dropping down from the delivery-pipe G upon that portion of the carbid coutained in the outer end of thebasket. The gas generated passes through the pipe J from the generator A into the bell B2, so that the latter rises in the tank B', and in doing so moves the bell B2 and pulley I', together with the rope I, upward to impart an upward swinging motion to the pipe H, so that the free end thereof is raised above the level of the water in the tank B', and consequently the supply of water to the pipe G is shut off. The generation of gas now ceases in the generator A. lVhen the gas in the bell B2 is used, then the bell gradually sinks, and in doing so permits the pipe II to swing back into a horizontal or downwardly-inclined posit-ion for the water from the tank B' to flow through the pipe H to the funnel G'1 and to the pipe G for delivering the water in drops to the carbid to generate a fresh amount of gas. The residue or hydrate of lime from the burned carbid readily drops th rough the wires ofthe basket D2 to accumulate in the receiver C. A new supply of carbid is continually fed to the basket from the superimposed magazine F. Thus it is evident that the generator is completely automatic in operation and a large amount of gas can be generated before a refilling of the magazine F with calcium carbid is rendered necessary. VVheu the carbid in the magazine F has all been used, the valves J7 and J3 are closed, and the cover A2 is then removed from the generatorcasing, together with the pipe G, supported on the said cover. The magazine F can then be removed, and finally the ash-receiver C, with the basket D2, to permit of emptying the ash-receiver of its contents. The several parts are then replaced and the magazine F refilled with calcium carbid.

In case too much gas is generated then the bell B2 rises to such a height 'as to bring a vent-pipe L, carried by the bell B2, out of engagement with the water contained in the tank B', so that the gas in the bell can escape through the vent-pipe, which latter is preferably connected by a hose with the. outer air.

A guide I5, carried by the tank B', is provided for the free end of the pipe H to move in.

Having thus fully `described my invention, I claim as new and desire to secure by Letters Patent- 1.
